A 4-mi. stretch of highway that will connect Utah's two most populated counties opened on Dec. 20. 2025 — several months ahead of schedule, heraldextra.com reported.
The first part of the Mountain View Corridor freeway, which connects Porter Rockwell Boulevard in Herriman and 2100 North in Lehi, will serve as an alternative to Redwood Road and Interstate 15 connecting Salt Lake County to Utah County, according to the Utah Department of Transportation (UDOT).
The project debuted in 2024, and UDOT spokesperson Wyatt Wooley, said work beat the expected schedule because of strategic planning, "excellent work" by the contractor and favorable weather.
"We haven't had a ton of snow in the last two years down in the valley area, so that enables them to just keep going," he said.
Copper Hills Constructors, which includes Kiewit, Granite, and W.W. Clyde, has handled the largest segments of earthwork, paving and bridges.
The project marks an initial step in UDOT's efforts to build freeway infrastructure in northwest Utah County that meet the growing population demands of Eagle Mountain and Saratoga Springs, heraldextra.com reported.
The state of Utah supported the plans in 2024, providing $1.4 billion for two new freeways and a freeway extension.
UDOT is scheduled to start construction early in 2026 on turning 2100 North in Lehi into a freeway that connects the Interstate 15 and Mountain View Corridor, according to heraldextra.com.
"Right now, what you drive on 2100 North, it is a frontage road. And, so, there'll be freeway in between there that will connect I-15," Woolley said. "So basically, there's going to be a big U-shape at the point of the mountain on the north side of Lehi that's all freeway connection."
The following year, UDOT expects to start construction to extend Mountain View Corridor from 2100 North to Cory Wride Highway, and the east-west Cory Wride Freeway between Mountain View Corridor and Ranches Parkway.
The department also began construction on Pioneer Crossing Flex Lanes in September, according to heraldextra.com
Woolley said people living in Saratoga Springs and Eagle Mountain are "desperate" to have a free flow of traffic to get where they need to go, and these projects will provide that.
Saratoga Springs Mayor Jim Miller said the city grew by 52 percent from 2020 to 2024, to nearly 70,000 residents, while Eagle Mountain estimates a population topping 65,000, up approximately 44,000 people in the 2020 U.S. Census — a five-year growth rate of approximately 49 percent.
UDOT is working with the northwest Utah County municipalities to ensure their future city planning accommodates traffic needs, Wolley said, according to heraldextra.com.
"You have to build not just suburban areas, but development for businesses and things, so people don't have to travel so far for work, so they can work in their area where they live," Woolley said. "And then also not make so many cul-de-sacs and routed suburban areas so that cars can get through."
